How many exit signs are required in buildings/offices?
Most commercial spaces and office buildings must have two exit routes. Exit signs should be posted along all corridors, hallways, stairwells, entryways, and exits that indicate the direction to the nearest safe exit. According to OSHA standards, "all exits and exit access doors shall be marked by an approved exit sign readily visible from any direction of travel. Exit sign placement shall be such that no point in an exit access corridor or exit passageway is more than 100 feet from the nearest visible exit sign.
